Oh! I think this might be caused by a 3rd party app. Let's restart your phone in Safe mode to test this out. (Instructions are here) Let me know if you see any changes!
Glad to hear it! Feel free to reach back out to me, or any other mod, if you ever need more help!
Hi. No matter what the time is set on my screen timeout in about 10 seconds. This is the 2nd S8 I had with this problem. The 1st S8 I had, my carrier replaced it because of this issue, but same problem with the new one. I turned off the security features as well as the battery saver features and nothing helps. This is a huge problem for me and countless others accordingly to the internet.
